I'm sure we are not going to come to a meeting of the minds on this and I understand your reasoning but there is something different about pit bulls. I am listing some sites about attacks on owners and their family just to make the point that attacks are not always on strangers. I know other breeds might do the same but it doesn't appear to be as prevalent as pit bulls.

Please note that one of the attacks is about a proponent of the pit bull who I'm sure argues that it is not the dog but the owner who is to blame.

Well, we can agree to disagree, but at the least I'd ask that you look equally as hard for their examples of caninely heroism before passing a permanent judgement...

Here's one:
